Is It Time to Give Up on Dark Matter?

So I’m Mike Lemonick. And I’m Lee Billings. And we’re going to talk about dark matter. Just a few weeks ago, Vera Rubin, a very eminent astronomer, died. And many people think she should have gotten the Nobel prize for her early measurements that suggested the existence of dark matter. It’s a grand picture that comes together and every single piece of this puzzle says ‘Dark matter exists. It’s real. It’s about eighty-five percent of the universe.’ Vera was looking at the rotation rate of galaxies and she was noticing that essentially this thing was spinning around faster than it really should be able to hold itself together based on all the luminous stuff- the stars and things we see in it. So that suggests there’s something hidden- not luminous, dark-that is holding it together. With gravity. With gravity, right. When you look at clusters of galaxies big collection of hundreds of galaxies that are kind of a clump they’re orbiting around each other and it’s sort of the same thing they’re orbiting too fast, and if there’s not some invisible matter whose gravity holding it together they should be flying out into the universe. Right. So there’s another thing with clusters of galaxies. Einstein showed that big collections of mass can bend light from things beyond, like more distant galaxies. And we can see that lensing but the amount of lensing we see comes from something much more massive than the galaxies that are visible, so there’s some kind of matter there whose mass is bending light. Again that’s consistent with dark matter. And we can also look back to the cosmic microwave background radiation and we can see kind of imprints. It’s subtle but an imprint within that radiation that suggests ‘Hey, there is some kind of dark matter active even then.’ So then the question is: What is it? And early on I think there were two ideas MACHO’s of course. That’s a Massive Compact Halo Objects which are supposed to get these big dark things, like planets for instance or even brown dwarfs, that float on the outskirts of galaxies. But the trouble is you already mentioned Einstein’s lensing and things. You know, we have these objects can bend light. We look for lensing and shadows of those objects in the halo of the Milky Way and other galaxies. And we just don’t see enough of them. Right, so the search has really focused over the past 25 years or so on particles. Astronomers called them Weakly Interacting Massive Particles WIMPS Very cute. So we’ve been looking, and we’ve been looking, and so far nothing. So far nothing! Some tantalizing signals but they all go away. So then the question comes up: Is it time to throw out the whole idea of dark matter? And people have suggested that what’s really wrong is not that there are these particles out there we can’t find. It’s that we don’t understand gravity well enough. There’s a modification to Einstein’s gravity that would explain some of these things. Yeah, and I think we have to admit that’s plausible but is that the most plausible, the most parsimonious solution I’m not sure if it is. So if astronomers aren’t yet ready to give up on Einstein’s theory of gravity, why haven’t we found these particles if they’re out there? Well, it’s it’s tough to look for them. We don’t quite know exactly how massive they are, exactly how they interact with ordinary matter. It’s a needle in a haystack where the haystack’s the whole size of the universe essentially. One analogy would be that we’re trying to build a net-the net being the detectors that we can use to find these WIMPS- and so how big do you make the holes in your net to make sure that you’re doing a thorough search? I think that you’ve got to make all sorts of different nets of different sizes and that takes awhile. Takes a long time. Could take hundreds of years, in fact. So if they don’t find it next week, the theory is still good. Yeah, the theory is still good. We should not throw out Einstein’s understanding the universe quite yet. Okay. Dark matter, there ya go.

So desperately sad, holding onto Einstein's model of the universe. 😂😂😂😂Will be so hilarious when they finally have to concede that their isn't any such thing as gravity. They've misinterpreted the electric Universe interactions of electrical charge forever.

Hey! You! Im from RUSSIAN FEDERATION!!!!!! Well clean your ears and be quiet with the hacker from Russia! Do you understand???!!! Very well, american pendos!!! But now eat some kilograms of your ugly potato free and be quiet with all RUSSIANS!!!!!!

Dark Matter seems to be invisible to EM spectrum probings. Dark Matter is a label for something all around which exerts a gravitational force (warps spacetime). It's assumed to be matter with Calabi-Yau shapes in vibrational states sufficiently different from normal matter (but also with more than 90 percent of its mass being the energy of gluons, binding energy, the same as it is with normal matter). And therefore it seems that the vibrational states of this DM doesn’t allow the 'coupling' interaction with photons — so it's not detectable using only the electromagnetic spectrum. Dwarf galaxies retain(?) or collect more DM than the larger colliding galaxies with more rotational energy. Is this a reliable clue to the mystery of DM? Most large galaxies have grown by collision. Are dwarf galaxies older and were able to collect more DM in the beginning?

No forward progress on the search of dark matter for nearly 80 years, but not getting the hint 😉MACHOs not observed, WIMPs not observed, and now super symmetric (SUSY) particles NOT observed despite millions of collision experiments at the Large Hadron Collider. Since WIMPs depend on SUSY particles, then now WIMPS are in trouble.Also super symmetry is in trouble, as is string theory which depends on it.No string theory –> No multiverse.No SUSY –> No WIMPs –> No Dark Matter –> No big bang, which needs dark matter to make galaxies, clusters, and superclusters coalesce in a short-short time of 14 billion years.Aren't you uncomfortable that the "main" explanation for the universe depends on four hypothetical layers (SUSY, WIMP, Dark Matter, Big Bang)?When will you admit that you do not know?

One single experiment caused this mess. And, now, you're lost, in quantum land. Believe me, gravity, dark matter, are easy to solve, if logic is used. But, hey, so sad, shame on you, you gave up logic in quantum land.

The universe is a vast electromagnetic plasma that has no need of so-called "dark" particles or energy for it to work. The universe operates on a simple principle of self organization due to electromagnetism.

They only keep coming up empty. I rely on the real sciences of what we can collect and observe. We can observe the effects of static electricity that helps to bring things together, such as raw metals that touch each other and make a molecular bond, instantly as if welding them together. We can see the effects of gravity, right here on Earth. I believe that we do not need to muddy up the study with delusions and fantasy just to keep the grant money coming and stay on that same course because of peer pressure within the science community. All we have is the basics of everything out there starting with gasses and dust that are not illuminated. Gravity is not a mystery. We understand it quite well. Unfortunately, because of the acceptance of theories as facts, we have not made advancements in this field. We should have free energy and be further along with the exploration and study of space.

Any expert in electromagnetism and particularly magnetism, knows that the mass of an object changes with the strength of its magnetic field. it is bull shit, if not moronic, to assume the mass of a galaxy can be known at all levels. All of this crap has been solved by other fields of study, Why do astronomers believe other fields of study have nothing to contribute to interstellar science, which has become interstellar seance? There are two possibilities. They are dumber than Joe Blow, or they already know they have shit in their pants. Both types will play the conceited ass-hole, which is entirely fear-based.

The thing is if dark matter makes up such a high percentage of the matter, then there should be some around us. And even if we can't see it, we should be bumping into it, or see it's effects within the solar system but we don't. I think the odds are that just like you have Newton on human scale, quantum on another scale–Maybe gravity acts differently on a galaxy scale.

One of the things that I really don't understand about the almost universal (and only marginally challenged) acceptance of dark matter is how cosmologists don't think it's plausible to think General Relativity might need modifying at extreme scales (not exactly unprecedented as that's exactly what happened to Newtonian Mechanics), so instead it's far more plausible to theorise a completely new particle for which we have no direct evidence and no reason to think exists – how does that work??

They keep saying "ah but dark matter has to exist because we can see its effects! So we know the matter is there!" Uh no, we can observe a phenomenon that defies our current theories, which you attribute to a type of matter we haven't seen yet. Stop using the phenomenon as evidence for the thing you're attributing its cause to.

Have seen a video here in YT : “ dark matter is a myth “ uploaded by Einstein’s universe without Big Bang, that seems to well explain why this stuff isn’ needed at all to justify the abnormal velocity of galaxy stars. In my opinion dark matter doesn’t exist.

I think dark matter can be explained by misunderstood time dilation. Since time and space are relative, from our perspective the spiral galaxies will look like wheels held together with spokes. But if we were there it would feel and look normal.

Answer…yes it's time. Dark Matter is as real as luminiferous aether was. We need to figure out gravity and throw dark matter behind us IMO. Why do we always ASSUME that gravity = mass; my theory is that space-time is kinked WITHOUT mass.

Late 1800s, scientists couldn't figure how radiation and light travel through space without medium. Created "Aether" to explain the phenomenon. 1920s, oops, "Aether" doesn't exist. Light is both particles and waves. Nowadays, scientists couldn't figure how galaxies hold themselves together without enough gravity. Created "dark matters" to explain the phenomenon. Probably sometime in the future, oops, "dark matters" don't exist. Universe is electric. — see the connection?

What about all the energy between masses – gravitons, photons, E/M fields… E=mc^2. What if all this energy flying around contributes to the "missing mass"? Large enough pools of gravitons creating their own gravitons, etc. Yeah I don't know. But has any math been done?

Dark matter is the natural conclusion of physicists in order to reconcile observable phenomena with the accepted structure of the physical universe. This is a solution in search of evidence, though, and the evidence just isn't there. The longer this state of affairs continues, the more physicists must eventually come to the reluctant conclusion that, despite all the tests that Einsteinian physics has passed, there has to be a fundamental flaw in its conception on the macrocosmic level. And if dark matter doesn't exist, but is instead an uncalculated effect of gravity, what does this further say about the equally undefined case of dark energy? One way or another, a revolution in physics is in the making… and its solution may prove the key to the understanding of the very basis of the universe.

The dark matter is inferred from a bluer Doppler shift towards the outer edge of a spiral galaxy. To explain this phenomenon, all you need to do is to account for gravitational redder shift towards the core of the galaxy.
